To all 'whom it may concern `Beit knownv that I, JAMES K. DARBY, a citizen of the United States, residing at Day'- ton, county of Montgomery, State of Ohio, have made a certain new and useful Invention in Paper-Making Machines, of which the following is a specification.

Thsinvention relates to paper making machines. v

The object of the invention is to provide a paper making machine which is simple in structure, ellicient in operation and economical of manufacture and maintenance.

Further objectief the invention is to provide a paper making machine so constructed as to allow the ready renewal of the forming wire Without removing any rolls from the machine.

A further object o f the invention is to provide asimple, quick and easy Wire replacing apparatu A further object of the invention is to provide a paper making machine so constructed as to allow the ready renewall ot the forming Wire Without removing'any rolls from the machine and to level, line and clean the rolls while in their usual. position.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as Will be more"fully hereinafter set forth, as shown by the accompanying drawing and finally pointed out in the appended' claims.

y Referring to, the drawing:

T he same part is designated by the same reference numeral Wherever it occurs throughout the several views.

Referring to Figs. l and la the combina-y tion of which shoivsa usual structure, of"

Fourdrinier machine, l designates the endless tvire, :2 the bottom couch roll located in block 3 and held therein by pins 4 supported by the couch side housing 4% 5 `designates .the top couch roll and 6 a guide roll. The'v latter is also supported by suitable hearings in. the couch side housing. The upper conch roll 5 is normally supported in its operative position with respect to the lower couch roll 2, as shown in Fig. l, by means of a bearing formed, for example as one illustration of the invention, at one 'end of a frame, Q00 which is pivotally supported as at Q01 by a stationary frame 202. The other end '203 of this frame permits means, npon counterclockwise movementV around the pivot 201 in the form shown, for moving the upper couch roll 5 away from the remainder of the machine, i. e., away from the breastroll. Suction boxes 7 are provided with the suc-A tion box table rolls S and Wire l passes thereover and beneath the dandy roll 9 and over table rolls l0. ll designates the breast roll and l2v the carrying rolls disposed beneath the table, one of which, for example, vas designated at 12B, may be a stretching roll to maintain thewire l. taut. A Water connection for the lsuction boxes 7 is shown atI 13, `The housing for the breast roll is shown vat 14 and is provided with afboss 15 there,

l which4 operate on for the purpose which will be hereinafter described. The housing 3.4 is provided with a screw 16 for adjusting the forming eleva- -tion of the wire as is usual and Well under` side housing en and ere locircd to the housings 1li and e by the look pin 9.8 as shown best in Fig. 3. The table rails 20 and 22 on opposite sides of the machine extend from the breast roli 11 te the guide roll 6 and are in two sections shown, the breast roll end of thetable rails on opposite sides o the machine beingn designated' 20 while the conch roll end oi" the table rails on opposite sides of the machine being designated-22.

it the breast end of the machine the table I raiis 2G are connected by means of the cross beams 21 passing under the rails 2O and restmg on the raiis 18, see Figs. 1 and 1,

The tops oi: table rails 2G are provided withy blocks 25 above or in .une with the cross.

beams Qi. "it will be noticed in Figs. 1 and i. that the biocirs 25 on the table rails 20 extend above the wire l elevation as formed the table rolls i0. `The reason for this arrangement will be described. hereinafter.

i machine are supported by means of the Llf) The'table rails 22 at the couch end of `the crossbeams 2'? which in turn are su ported by rails 18' and bioclrs 26 which are .istened to the raiis i8 by locking devices 23, see Figs. 1, 1 2 and i. A chain hoist 3U, mounted on a, suitable nlley 31 is provided at each end of the machine and supported by the frame work thereof fora purpose which Will be more fully hereinafter set forth. The tore going briefiy cnumerates the various parts which gc towards making up the Four-drin ier machine ofthe nsnal construction, the forming Wire 1 being made usually of copper wire, woven in an endless belt passing around various rolls, as the paper forms on the table of the machine. The Wire l is so constructed for the purposes required that it is very easily broken, and in fact can be destroyed with the tip oi the finger, These wires alie usually "from to 232 in width and-travei as fast as G per minnte. Frein this it is obvious. to maintain the 'forming Wire in operative condition, the same mest be handied with extreme vcare to guard possible destruction or '1ngnry, which i. ccssitates winding a new @vire on the apparatus, involving littering np machine .and great Waste of time7 4time is from one hundred and 4fifty to aplabor and expense. It is customary in stringing the wire 1 on the Fourdrimer to remove all of the rolls of the machinevvith the ex#v ception of 4the bottom couch roll, then lifting the front end of roll 2 by removing the supports therefrom, slip the Wire 1, previously Wound on long poles, for instance, as shown at 40,.Fig. 8, over the roll 2, then stretch the Wire back to the' breast roll 11, and then replace all the rolls, suction boxes, and savealls by passing them through the Wire 1. Should any mishap occur, the wire l-is damaged beyond use or, at the best, has a very short life on the machine, giving a great deal of trouble and involving a great waste in defective paper, in the continuous operation of the machine and involving a vast expense as the Wires now in use cost from one hundred to' a thousand dollars each. All this is in addition to the time required to replace the wire with an undamaged one, which in practice, takes from two to three hours, at the least, and as the productive value of the mach-ine in normal proximateiy four hundred and fifty dollars per hour, this loss it willbe seen is` enormous, especially when it is considered that the normal life of a wire is from six to eighteen days. Likewise, in removing the various rolls 'from the machine, should any one roll receive a small nick or dent, or other defacing mar, this nick or dent, Ior other defacing mar, will destroy the wire in operation and in fact any and all wires that may be subsequently installed until the nick, dent or other `defacing mar is removed from the roll. This may be more apparent when it is considered that practically all of the rolls and in fact the entireuFourdi-inier parts are constructed preferably of' copper or brass.

It is among the special purposes of my present invention to provide means to string the endless -wire l without taking the rolls from the frame of the machine, thereby eliminating any danger oi' the rolls being damaged by handling and in addition thereto toreduce to a minimum the possibility of injuryto the Wire itself and still further in addition thereto to' reduce the length of time required for the replacing of a damaged or faulty wire, to a very short time and with a minimum ramount of labor involved. As illustrative of the principle of the invention involved and referring to Figs. 1 and 1", the Fourdrinier parts are in position as shown in these figures.

. The Fonrdrinier proper may conveifi;v` lently be divided into two parts; the breast 1 roll or truck end and the couch end. The former consists of the breast roll 11, breast roll bearings 56, wheels 17, table rails 20,

cross beams 21, connecting table rails 20,

blocks 25 on top side of table rails 20, in

line with cross beams 21 as shown, sevealls 50, partitions 51, gate system 52, 53 and 54,

(for temporarily supporting the table rails.

22 at one end) and deckle pulleys 92 )with suitable bearings 92", consisting of a journaled bearing having an adjustable stanchion 192, which is threaded to receive locknuts 193, for holding the stanehion in the table rail 22. Bolts 29 (Fig. 3) connect the table railsi22 to the housings 4, for holding this part of the housing in position and to prevent ,tipping when the removable block 3 is displacedand the dandy roll 9 and stand removed for restringing the Wire.

Rails 18 may conveniently extend from the couch housing Liln to the breast roll housing 1% and be locked thereto respectively by lock pins 2S. These rails support the breast or truck end of the machine and the cross beams 21 rest thereon and are securely bolted thereto by the bolts 21a. At the conch end of the table blocks 26 extend .from the cross beams 2i'. above the rails 22 to the rail l 18, and are lock-bolted thereto at 23.

To replace an old Wire withv a new one, the old wire is first removed from the machine in any convenient or ordinary manner. The ordinary Way is to break the Wire, generally across the fa'e of the lower couch roll, b v cutting the saine, or in any other way, and the machine is operated so that the Wire .is discharged from the machine at the couch end. The nest sten 'ir process ot restringing consists in rodi ig the support of the upper couch roll by means of the arm 203 and bearing 200 pivotallybsupported intermediate its ends, as hereinbefore described and shown in Fig. 1. This operation swings the upper couch roll 5 away from the remainder of lthe machine, i. e., away from the breast roll, and thereby enables a complete breaking of the-front face of the machine throughout its entire length and permits the new Wire to be passed over the entire machine in the forni of an elongated loop, the dimensions of which will depend upon the degree of relative movement of one part of the machine 1vitlrrespect to the other, as will be more fully hereinafter described and which, -as will be readily apparent, can be controlled at will. it is obvious, of course, that the couch roll 5, once swung out of its normal position, vwill be retained there during 'the restringing operation in any Suitable manner, for example by blocking the same. ,Ifl it 1s now desired to resti-ing the Wire,

lock-bolts 21si and 23 are removed and the jury posts placedin the position shown in Figs. 1 and 1a, for the purpose of supporting the table rails 22 at one of the blocks 26. The chain hoist 30, operated by pulleys 31. now engages the rails 18 at both ends (as shown in Figs. 1 and 1") and takes the weight from the lockbolts 28. Lockbolts 28 are then removed at both ends of rails 18. The couch ends of the table'rails are now supported by the couch housing 4B.

The jury posts 55 support the other ends of the rails and hold the couch end of the table in the position shown in Fig 2. All the lockbolts having been removed, the rails 18 are supported by the chain hoists 30, and rails 18, in turn, support the truck end by means of the cross beams 21.

Previous lmention has been made of.

notches or depressions 19 in the rails 18, in which the wheels 17 of thetriick end are normally suspended. The rails 1S are lowered by means of the chain hoist 30, andthe truck end, 'supported free on the rails 18, alsov lowers with the rails until the breast roll bearing 5G strikes the boss 15 fastenedto the breast roll housing 14. This causes the truck end to slide forward on cross beam' 21 along the rails 18,.until the truck Wheels 17,

Anormally in the notches 19of the rails 18,

lift out of the notches 19 and in so doing take the Weight fronithe truck end and of the cross beams 21, thereby causing the truck end to be supported on the Wheels 17.

The declle pulley 92 and stanchion bearing 92a are now taken from their normal position, as shown in Figs, 1 and 1*, and

placed on the auxiliary bearing 93, situated on the ruler bar 90 of the deckle frame.

lThe truck end of the machine Anow rides on the wheels 17 and is lowered a sufiicient distance,by hoists'SO, to enable the truck end to be passed forward under the couch end 'to the position shown in Fig. 2. il'ith the truck end lowered. and shoved forward under the couch end, the machine is doubled up so that the blocks 25 on top of rail 20 rest on the bottom of the rail` spacing the -v rails 20 and 22 apart, so that in lifting the frames and rolls together no pressure will bear on any of the rolls.

By thus telescoping the' Fourdriuier as described above, I have reduced the cxtreme normal distance between the couch roll 2 and the breast roll 11, ingl me a better Working clearance in stringing the Wire: also giving a better advantage for lifting the traine as the slack Wire is slipped over the faee'of the rolls.

Furthermore, owing to the increased weight of the wire used on Wide, high speed modern paper machines, I' provide special means for carrying said wire. across the face of the machine rolls. and also for removing the same from the shippingbratehand Lwill j beam 21 at 21D of the tluok omi.

that 'iba wire truck arrngzement is exbe and 2, it WH be noted that tho box 4bearings and as the poles are frequently Eongor ESG than the wire and project bevond the edges as sai-inept considerable exit-onse where dif" ferent sizes of machines have to be rewired. reassemhle the machine after ,the wire is Jtime pnt in place, the block'3 u nder the roll 2 is replaced `and fastened in position y means ot the pins et; the chain hoist 3G is again 'fastened tothe rails 1S.,the' jury post is again swung intouplace, the rails 18 are raised by means ofthe hoist' 30--50 as to take the Weight Lof thetruck end` the wire truck 60, breast lift 63. vand Aeoueh'lift 62 are then removed and agaln'the' machine is in the position and condition with respect to the various elements, s shown in Fig. 2 ready toA be extended -to `its proper `position by a reversal df the. operation hereinbefore described, which proper position is shown by the combined Figs. 1 and l, The spread pipes G4, 65, whichwere extending through the wircl are then taken out of the way.

In Stringingr the wire l aty the present time great care must be taken that the wire is not dan'laed in anv way, and also that the wire must be strung true and in line so that during the operation of the machine, the same `will travel in a perfectiy straight line, thu\s preventing excess of wearingr lon the edges of the wire. v l j The wire'ibeine slipped over the rolls` as shown in Fig. 2, by the slack irregular line I, the Wire spool, supported by trucks 8O and G6, is then in position to unwind as the truel; end is carefully moved back to the position shown bv the combined Figs. 1 and Tia. Thereupon the wire 1 on the Spool unwnds nntilail of the wire 1 is off of the wire poles l0, one of the poles 40 being on the inside wire l, is passed through. and both poles 4l) beingy newl empty are removed with the trucks 66 and 80. The wire 1 now' has more or less slaclr and it is at 'this point that i provide means for insuring that the'.

Wire put on straight and in true alignmnt.- To insure the wire beine put on straight so as to runin a truejline, the couch roll 'f' roll 1i, alsaseveral of the rolls internos between these two rolls, are prete ably primitied with a ring marked on or neer the ends of the faces tlnreof,` showing a troeiine for the edge of the wire i to toliow' as 'the truck end is moved hack to its proper position, thus insurins: proper alignment of he wire on the rolls.

` l also provide means to keep all of the Polis in proper alignment and level While the paper making machine is in operation,l Even when the paper malrlng machine is 1n operation, it can be ac^urately`determined what rolls are in alignment. In the present form of Fonrdrinier machines, it is neces- 'sary and customary to remove ,all of the This has never bt` i rolls from the machine except the couch roll 2 and breast roll ll in placing the rolls in alignment, and should a roll get out' of alignment, it often spoils the wire and several Wires which are successively employed thereon until the rolls are rc3-aligned .in their proper position. In my'present machine after the couch roll 2 aufl breast roll l1 are placed in-a proper position a boss bb is fastened permanently to the foundation plates on the front and back sides and so- ]ocatcd thereon that a plumb bob line dropped from the face of the couch roll 2 and the breast roll-1l coincides therewith, so that it is easy to determine whether or not the couch roll 2 and the breast roll 11 are in accurate position. This arrangement has a number of advantages over the present customary method vwhich consists in first linin;T the couch roll 2 and then line "the breast roll All with roll by passing a line varound both rolls 2 and ll. as the present method requires considerable skill. I also place on the foundation piates, additional bosses bb beneath rolls l2. The journals being accessible I strike a line through the center of the journals. The table rolls 8 and l0 sul vported on the table rail' 20 have extendedI journals so that -the bearings are supported on the table rail 20 which is slotted to allow for adjustment to 'rightor left as shown at S. Central. with the slots are ma'rks indicated at T placed on the rail 20 central to the extending journals of the rolls 8 and 10. The caliper eeler F placed on the rail 20 at the marks T is moved under the extending journals of the rolls 8 and 10 and proves that the rolls 8 and l0 are in line and level as will be readily understood. Should the caliper feeler F prove that any roll 8 or L0 is out of line or level on the rail 20, the operator loosens the lock nuts that hold the bearings of the rolls 8 or l0 to' the rail 20, moves the roll to the proper line or level and again locks the bearings to the rail. At the present time, it is customary to place the stem of the bearings of the rolls 8 and 10 into al hoiedrilled into railst20 allowing,r no` Vof the bearings often ts loosely in the rails 20 the bearings wobble, the rolls 8 and l0 r'un out of line, crowd at the shoulders of the journals, the journals become sprung,

thereby causing therolls to ,wobble in their bearings and jump, causing marks or a weak .spot in the paper, which causes the paper to break, Often the rolls 8 or 10 stop turning, which causes the wire 1 to Wear a flat side on the relis so that if the rolls start to turn again in this condition they mark the paper lnd'wear ridges in the wire 1, causing the wire to have a ve short life.l To overcome this recognized ob]ection to the present type I of F ourdrinier machines, I piace a hollow 1 ing the tube 35 securel tube 35, see Fig. 12, threaded on the outside the bearingl 3i is re'uired to be raised the hollow tube 35 is loc ed securely to rails 20 end 22 and cannot wobble.

i I Also by means of the small motor M on the rail 18 (see Fig. 5) means are provided 20 for turning the rolls by power. My reasons for this arrangement are as follows. In.pa-

er. making operation, certain chemicals aotlng with the water employed cause the relis to. corrode, and if there is any scale or corrosion on the face ofthe rolls it has a tendency toause thewire yto become defective. 'It is thelpresent method to use acids, or before replacing a wire to scrapethe eorroding scale off of the roll. I propose, before re =placing a wire, to attach a small motor to theen'd of any of the journals and sand paper therolls olf by power, without taking' .the rolls outo the freine of' the machine. It Jis understood that the motor is removed when the machine is in operation.

At the breast-and above the Fourdrinier table is located the deckle frame consisting,

of the ruler bar 90, supportin side posts 91, deokle pulleys 94, breast boar 95, head box 96, Slicer 97, adjustable* supports 98., brass plates99, and thewire -Slicer 100, auxiliary bearing 93 and pulleys 92.

Referring to 'Figs-1 and 1, it will bev noticed that the 'posts 91 are made adjust able, so that the postsv can be adjusted to any desired' length. The smallest end of.

the posts 91 slide in and out. Fastened to the upper partlof thel post 91 is an angle late 101,. Thepurpose of this angle plate is threefold. First, in lowering the breast `,end of the. machine, when about to put on a wire, the deekle frame will also lower, but I provide an angle plate 101 fastened` to 'the upper section of the adjustable post 91 so that in lowering the table rails 20 the deckle frame also lowers until the angle plate 1131 rests on the shoulder of the lower section "of thejadjustable post 91, where the deekle frame rests while teleseoping the table frame as hereinbefore described. The boss or angle plate 101 rests on' the rail 18 should the machine be of the shakeless deekle type.

While the angle plalbe is not fastened to the rail 18, the rail by means of the angle plate et all times nsupports the decirle frame 1eme lwhen the machine in operation, whether ,ornot the decsle frame is vibrated. As the rails 18 support raiis 20 vand 22 any ehanye inelevation of, raiislli changes rails 2Q and 22, and changes the elevation of `the deekle frame as well. The relis 2() and 22 support the table rolls 8 and 10. The foils 8 and 10 with the Wire l-.eoniprise theforming table over which the paper ilows. The Slicers 10D attaelied to the deelde trarne therefore 'adjust themselves with the rails 2Q, @and 1S.

The deckle frame, breast board 55, head box 96, are all coupledtogetiier. The breast board S5 rests lightly on the housing 1li sind is supported by the adjustable po@ 98 with the screws 102 and 16 coupled together, to ao'rd adjustment of eievat-ion of the breast and of the machine. The adiustable ar rangement consists et the breast housing i screw 16, head box screw 1132 sonneeted by the shaft 103, su ported by brackets 194i and 105. At the roast housing end o1'- the shaftl'gthe gears 1115 engage the screw At the head bor. end o 'the shaft 103 the gears 10'? engeire the serein 1G93. The

shaft 103 is operated, 'as shown, wheel 103. ghe sersws and 102 being of the same nimh, and the gears 166, 197 heing. of the same ratio, the edj'ustment bev tween the housing 1% and the headubox 96' 1s enact.- The dechfle .trarne sind head nos are independent othe vibrating motion of I the Fourdrinier table, and the adustable este 98, 'reiieving the weight of the head x 9%, takes the weight eti o the housing' 1 4, as will be readily understood.

The Fourdrinier parte at the breast end of the machine, vibrate from side to side, a suitablearrangeinent being shown 115. As shown in the'I shaker 1,15 is ai'ladhod te 'the breasthousing 14, and-as 'die housing 14; supports the rails 18, by means' of Ythe leelrbolt 2S,

the rails 1.8 also vibrate with the breast housing 14, and as the rails 18 supportthe ,by the hand v drawing Figa the j rails 20 and 22, of the wire forming table,

,the vibrating motion is conveyed to the Wire .forming table' fails 2O and 22 by the rails 18. Therefore; both the raiis 1,8, 2G and 22 vibrate by the shaker arrangement;

Previous mention has been made to the angle plate 101 fastened te the posts of the decirle frame, and as the posts 91 are telescopic, the angle plate 101 entends over on the rails 1S, and when the machine is in a normal running position these angle plates fastened to the upper part of the tolescopie post 91, supports the deckle frame by bearing on the rails 18. Therefore the rails 18. adjust the elevation' of the deelde frame, by means of the upper section of the telcseopie posts 91, supported by the angle plates 101, bearing on the rails 18., This is of vital nnportanoe owing to the fact that .mitting the rails 18 to slide to and f ro free beneath the angle plates 101.

f )Mit is now desired to vibrate the. decklc xtine, the telescopic posts 91 are released at,

the floor by removing the bolts 91B. A. breast board bracket heretofore hearing lightly` on the housing 14 is bolted to the housing 14 at 05". The headbox 96. secured to the adjustable post 98, is released from the posts 9S by removing the bolts 96a. This permits the head box to slide back and forth on posts 98 as the entire machine Vibratcs. It

ywill be understood that the elevations of the forming wire, the deekle fraaie and the head box 96, is at all timesregnlated by the two elevation screws 16 and 102, and it is absolutely impossible for the forming wire (in changing elevations) to come in lContact with the Slicer and thus be da stroyed whether the deekle and head box vibrate or not.

Reference has been iliade to the savealls 50 with partitions 51 located beneath the table rolls 10 into which the Water used in torining papers filters through the Wire 1. The

' savealls 50 consists of a shallow Water-tight v box, see Fig. 4, the bottom resting on beam Q1 and the sides extending to the same elevaf tion as the forming table, making it possible to submerge the rolls 10 completely. Extending across Vthe savealls 50 are .the partitionsl 51 dividing the sarealls into three scetions; each section having a trough 111 fastened permanently to the saveall 50. The sareall system forms a part of the truck end of the Fourdrinier and is not removed from the Fourdrinier at any time, but if it should be desircdto wash out the sarealis before putting on a wire, by removing one or more ofthe table rolls-8 from their bearings and laying the roll or rolls over on top of the accompanying rolls. enough room will he. made to clean the sai'ealls and the troughs as desired.

As shown in the drawings, the -sare'alls system vibrates with the Fourdrinier table and as the sides of the sarealls 50 are at the saine elevation as the wire. the partitions 51 being lower than the forming Wire` enough clearance is allowed so ythat the Wire 1 will not be damaged in any way by the partitions. By regulating the flow ot' Water into the savealls and then into the trough 111 the savealls 50 by closing the flow into the trough 111, and as the Water, cannot escape through the'wire 1 into sawealls'y 50, the water passes over therpartitions 51, forming a lake on the wire hol ng the Water in the liber and malring the fiber carry up the water to any de sired point' ot the three sections of the saveall system. This has the same effect as changing the forming elevation or changing thenatnl'e of the liber, as in free or slow stoclthe Word free meaning that the wie ter escapes from the stock easily, and thc Word .slow" that it does not csrapefeasily.

A better luuderstanding ot' the method of regulating the Water 1Within the savealls 50 cali be'had with reference to Fig. 7 wherein the partitions 51 diride the. sareall 50 into three sections. In this View, are the gates, :33 the openings in the gates` 54 the eponings in the bottoni of the sai'ealls 50, 111 the trough fastened to 50 direct-ly under theopenings 54. Referring to Fig. 9 it will be noted that at one section the gate 52 is in such a position as to close all of j-.hc openingsl 5l so`tl1a't no filter Water can flow into the trough 111. 'At the next section, the gate 5i). is positioned to permit the filter Water to pass through they i artially opened gates 5:). through 54, into t e trough 111. The next sect-ion has the gate-52lwide open so that all filtered-Water may pass through the openings 53 through 54 into trough 111 then into the vent trough 110.

The advantages of this arrangement em.- -bodying my invention 'are obvious, principal among which being the control at will of the n'seof various fine grades ot' paper. In regulating the iltei through the Wire 1 by .fiooding the savealls and by flooding;` that section of the savealls next to the breast roll 11 first and by passing the Waiter over the partitions 51- from one section to the other until thelastsection from the breast roll l1 is reached, then by letting all the water lil-` tering through the wire 1 escape through the` one trough 111' by closing the other troughs, the rush of excess filtered 'water through the last section 50 into the trough v111 has a tendency to form a Siphon andfcause a forced suction on the filtered nater in turn causing` the filtered water to pass through the Wire 1 by a force greater than gravity and therefore causingthc iibre orming ou the Wire 1 to. give up more Weten than under natural tend-l encies. This, of course, causes the fibre to br drier and, stronger than otherwise.

The guide rollG may he adjusted "by the usual automatic arrangement whiclris'not shown in the drawing. Whether or'not the guide roll is auton'iatically adjusted the saine has always been a source of considerable trouble and I have traced the trouble not to the automatic arrangement, which is generally employed for maintaining the same in alignment, but to the bearings of the guide roll itself. Assuming that the true normal position of the guide roll 6 should be at a wife 1, it mooi bo emolfoa f Fourdrinior machines consist o ioiis, any one of wiiioil may gei; o Iovei and thus 'ihrs guido vois iie aotomatio ariangeinon'; "ooutoff at one. omi hereinoeoro mentionefl, omino fue guide foil to move tile cofriagge, So as io Qompensnio im any pari; being out o iino. @The guio roli is moved out of lino in o diieoion opposio to Whatever pini is out in ihiougoou the Fomdrinier xiiaohino.
